2 Claims.

This invention appertains to colee percolators, and more particularly topercolators of such size and construction as to permit the economicalmaking of a small quantity of coffee (one cup) in a minimum amount oftime.

One of the primary objects of my invention is to provide a coffeepercolator embodying a cupshaped body, having detachably fitted in theupper end thereof the container or basket for the ground or pulverizedcoffee, which, in substance, forms a continuation of the body, thebasket directly receiving the cover for the percolator.

Another salient object of my invention is to provide novel means forpermitting the free insertion of the basket on the tube of thepercolator pump, and at the same time preventing upward movement of thepump relative to the basket, incidental to steam and water pressureacting on the dome-shaped base of the pump during operation of thepercolator.

A further important object of my invention is to provide a coffeepercolator of the above character embodying a minimum number of parts,which can be easily assembled and taken apart to permit the thoroughcleaning of the parts.

- With these and other objects in View, the invention consists in thenovel construction, arrangement, and formation of parts, as will behereinafter more specically described, claimed, and illustrated in theaccompanying drawing, in which drawing:

The figure is aside elevation of the improved percolator, with partsthereof broken away and in section to illustrate structural features.

Referring to the -drawing in detail, the letter P generally indicates myimproved coee percolator, which comprises a cup-shaped body I, formedfrom aluminum, or other suitable material.l As illustrated, the body Iincludes a cylindrical side wall 2, and a at bottom wall 3. The upperedge of the side wall 2 is rolled to provide a peripheral bead 4, whichfunctions to strengthen the body and to eliminate the formation of sharpedges. A pouring spout 5 can be struck directly out of the side wall 2adjacent to the upper edge of the body. This pouring spout is preferablyspaced a slight distance from the rolled bead 4.

The bead 4 forms a seat for the container or basket 6 for the ground orpulverized coiee. This basket or container 6 differs from the ordinarypercolator basket, in that the same forms a y continuation of the body,and the basket includes an imperforate cylindrical side Wall 1, and aperforated bottom wall 8. The side Wall 1 has formed therein in spacedrelation to the bottom wall 8 an annular bead 9. The basket or containeris adapted to be inserted within the top of the body, and the annularbead 9 rests upon the rolled bead 4 of the body. The upper edge of thecontainer or basket can also be provided with a bead l0.

The axial center of the basket or container carries a sleeve Il, andthis sleeve has formed thereon adjacent to its lower end an annularshoulder I2, which is adapted to abut the upper surfaces of the bottomwall of the basket. The lower end of the sleeve is upset, as at I3, inintimate contact with the lower face of the bottom wall of the basket.This forms a simple and durable means for connecting the sleeve with thebasket. The sleeve is adapted to receive the tube I4 of the percolatorpump, and this tube is con- .nected in any desired manner with thedomeshaped hollow base I5 of the pump. Water inlet openings I6 areformed in the hollow base.

A cover I'I oi any suitable character is tted in the upper end of thecontainer or basket, and after the basket is removed from the body, thecover can be placed in said body.` An annular bead I'I is formed on thecover above its bottom and engages bead I0, when the cover is inposition. The cover Il detachably carries the'glass top I8, wherebypersons can observe the functioning of the percolator.

One of the important features of my invention is the provision of meansfor preventing upward movement of the pump incidental to the forming ofpressure in the hollow dome-shaped base I5 during the operation of thepercolator.

To prevent upward movement of the pump, the tube I4 has struck outtherefrom, or formed thereon, an annular bead I9, which is adapted toengage the lower face of the basket 8, or the outstruck ange I3 on thesleeve Il. Thus, irrespective of the fact that the basket is supportedby the body, upward movement of the pump will be eliminated.

In operation of the percolator, the desired quantity of water is placedin the body I, and the ground or pulverized coiee is placed in thecontainer l, after which the parts are assembled as shown. y Upon theheating of the water, the percolator will function substantially in theordinary way, and when the made coffee has reached the desired strength,the percolator can be removed from the llame.

Changes in details may be made Without departing from the spirit or thescope of my invention, but what I claim as new is:

sesr

1. A coiee percolator for use in the making of substantially one cup ofcoffee, including a relatively short cylindrical body open at its topand having its top edge rolled over to form a bead, said body having apart of its side wall struckout to form a substantially V-shaped pouringspout, the top of which latter is disposed below the bead but in closeproximity thereto, a ground coffee container of less height than that ofthe body provided with a perforated bottom and having a peripheral beadabove its bottom, the lower portion of the container being receivable inthe body and having its bead engageable with that of the body, a pump inthe body having an upwardly extending tube, a sleeve receivable overtheupper end of the tube and having its lower end extending through thecontainer bottom and flanged outwardly to engage the latter `on itsunder face, and further having a peripheral flange which engages theupper face of the container bottom, said tube having a peripheral flangewhich abuts the outwardly anged lower end of the sleeve, and acylindrical closure for the container having a bead spaced above itsbottom, the container having a bead at its top engageable with the beadof the closure when the part of the closure beneath its bead is insertedin the container, said body, the container, and the closure being eachof substantially the same diameter, whereby the device as a whole is ofgenerally continuous and uninterrupted cylindrical form throughout theentire length of the body of the device, and the overall length of thedevice being such so that same can be grasped in one hand of the user.

2. A cofee percolator in accordance with claim l, wherein all of theaforesaid beads and the spout constitute the sole projections throughoutthe entire height of the device, the latter devoid of other handles orthe like.
